"Now why don't you jiggle those boobs for me, Jon?" Karyn, now Kyle, grinned as he said this, showing of her own assets as Jon tried to cover hers.
Putting her hands to her new mammoth (DD!) mammaries, Jon gave her friend a dirty look, "Not likely. And how is this supposed to be any better?"
Karyn gave a grin, "I don't know about YOU, but I'm kinda feeling better already. Now didn't I say to jiggle them?"
Jon grumped, but before (s)he could form a retort, suddenly her breasts started swinging and bucking side to side, nearly throwing Jon to the ground with each wild hop. "W-what?"
Karyn, aka Kyle, grinned, "Well, didn't you know? I control your body, remember? You're gonna keep shaking it until I want you to stop, okay?"
Jon loosed a light 'oomph' as she realized that her breasts were REALLY beyond her control, "Karyn, this is too much... ACK!" Then, Jon found that her legs, those milky white, femenine legs that Karyn had given her, just straightened up, thrusting her wide femenine hips into the air as her arms flew behind her, her breasts still swinging from side to side. "What are you.. ah, doi-YING to meee!?" Jon whimpered as her bare vagina became warm and moist, her breasts ending in hardened points that were apparently perfectly happy with swinging about at high speed, even as Jon found herself simply arching herself back, as though presenting herself to the world. "Karyn, this is wrong!" on shook her-his head in struggle against his, her own body, "Please, stop-gasp!" Jon's voice had changed! It had become that of a girl! "What are you doing!?"
Kyle grinned, this was so HOT! And it was making 'him' hot... and moist, apparently. But he wasn't ready to try sex as a girl, yet, but maybe later..., after all, he had the perfect toy, and playing with it was proving perfectly entertaining. At this point what he had was a girl, arched backwards on her hands and feet, her vagina in the air and her breasts swinging rhythmically from side to side as her head, slowly becoming more feminine itself, since Kyle had decided to go back on his word to stop at only half-girl, was showing a struggle as she tried to control her body, but it was Kyle who was in control, and he, she, planned to give her new toy a good working over.
